What are you looking for?
We’re heading to Guangzhou this October, and we’d love to see you there.
Rainbow will be at the 140th Canton Fair during Phase 1, from October 15 to 19, 2026. You’ll find us at Booth 17.1N14 in the Power Machinery and Electric Power section. We’re bringing commercial and residential chimney samples for you to examine up close. More importantly, we hope to hear about the exhaust challenges you’re working on.
Our commercial display sample has a 200 mm inner diameter and a 300 mm outer diameter. It uses a SUS 316L stainless steel inner liner, a SUS 304 stainless steel outer casing and high-performance ceramic fiber insulation.
You can see these materials and the double-wall construction for yourself at the booth. If you already have equipment specifications or a project drawing, bring them along. A conversation around a real sample is often the easiest way to identify which details need a closer look.
A commercial chimney is one part of a larger system. When we discuss a project with you, we want to understand the equipment it serves, the exhaust conditions, the route the flue needs to follow and how its components will connect. Those details help guide conversations about dimensions, materials, insulation and installation.
Rainbow works with commercial chimney systems for applications including generator and boiler exhaust. For a generator flue system, for example, the discussion goes beyond a chimney section to the flue ducts and related components that carry exhaust away from the equipment. We can use your project requirements to discuss a suitable system approach with you, rather than assuming that one sample size fits every installation.
The sample at our booth is a starting point for that conversation—not a substitute for reviewing your specific operating and installation requirements. We’d welcome the chance to work through those details together.
We’re also bringing a residential sample: a six-inch, black-painted double-wall chimney for a wood-burning stove. You’re welcome to compare it with the commercial sample and ask us about their different applications.
Whether you’re choosing a chimney product or planning an exhaust system, come and tell us what you’re working on. Questions, drawings and equipment details are all welcome.
